The Central Intelligence Agency researchers have been waging a multi-year campaign to break the security systems used by Apple on its devices.

The Intercept claims to have received documents outlining methods the CIA has considered to access data on Apple products. The usual talk of decrypting and vulnerabilities is present, but there's one technique in particular that seems especially nefarious. Reportedly, the CIA went as far as creating a modified version of Xcode (an Apple tool that developers use to make apps). The hijacked Xcode would unwittingly include code in the final app without the developer knowing. The Intercept's sources also claim OS X's updater (that automatically installs the latest version of OS X) was targeted with a modification that would install a keylogger onto your Mac. Fun. No word on if they're already trying to get into the shiney new AppleWatch.
